Abstract
The utility model discloses a kind of switch cubicle rectifier bridge, primarily of rectifier bridge, on/off switch coil composition, divide-shut brake coil is connected with rectifier bridge, and for solving prior art Problems existing, the technical solution adopted in the utility model is in parallel at rectification bridge output end and resistance-capacitance device.Resistance-capacitance device is made up of resistance, electric capacity.Compared with prior art; due at the output of rectifier bridge resistance-capacitance device in parallel; electric capacity both end voltage can not be suddenlyd change; resistance-capacitance device plays the effect absorbing peak voltage; thus to the effect playing protection of getting an electric shock; prevent from puncturing, effectively avoid and cause circuit breaker cannot normal deciliter phenomenon because rectifier bridge punctures.Above-mentioned resistance-capacitance device is arranged in the space of rectifier bridge input and output contact pin, and the mounting means of rectifier bridge is remained unchanged, thus side is all over manufacturing and installing.It is little that the utility model has divide-shut brake surge voltage, use safety, feature easy for installation.
Description
Technical field
The utility model belongs to technical field of electric power, is specifically related to a kind of switch cubicle rectifying device.
Background technology
In the transformer station run at present, 10kV switch cubicle adopts rectifier bridge to coordinate point usually, the structure of closing coil, with control circuit breaker deciliter.The moment impact voltage that traditional rectifier bridge divides at circuit breaker, close a floodgate is larger, rectifier bridge easily punctures, to cause point, closing coil bears larger overvoltage of direct current and cause damage, thus make switch cannot normal deciliter, very large threat is caused to the safe operation of electrical network.
Summary of the invention
It is less that the purpose of this utility model is to provide a kind of divide-shut brake surge voltage, and safer modified model switch cubicle rectifier bridge, to solve prior art Problems existing.
The utility model is primarily of rectifier bridge, on/off switch coil composition, and divide-shut brake coil is connected with rectifier bridge, and for solving prior art Problems existing, the technical solution adopted in the utility model is in parallel at rectification bridge output end and resistance-capacitance device.Resistance-capacitance device is made up of resistance, electric capacity.
Compared with prior art; due at rectification bridge output end resistance-capacitance device in parallel; electric capacity both end voltage can not be suddenlyd change; resistance-capacitance device plays the effect absorbing peak voltage; thus to the effect playing protection of getting an electric shock; prevent from puncturing, effectively avoid and cause circuit breaker cannot normal deciliter phenomenon because rectifier bridge punctures.
Above-mentioned resistance-capacitance device is arranged in the space of rectifier bridge input and output contact pin, and the mounting means of rectifier bridge is remained unchanged, thus side is all over manufacturing and installing.
It is little that the utility model has divide-shut brake surge voltage, use safety, feature easy for installation.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of modified model switch cubicle rectifier bridge.
1 diode, 2 resistance-capacitance devices, 3 resistance, 4 electric capacity in figure.
Embodiment
As shown in the figure, be in parallel at the output of rectifier bridge and resistance-capacitance device 2.Resistance-capacitance device is made up of resistance 3, electric capacity 4.Resistance-capacitance device 2 is arranged in the contact pin space of original rectifier bridge input and output, can not change original mode of connection, can not affect the layout of other equipment in switch cubicle.
Claims (2)
